Solved Plugin already Initialized Issue

I get this issue on start up where the plugin says it was already initialized. I tried reloading and that didn't work. It's the only plugin in the server; so that's not the issue. I've done a bit of research but just can't find anything that works.

Code:

Is it possible that your class has the Class of your Plugin has the same names?
If the way to the main-Class is the same, the plugin can't be loadet.
(plugin.yml > main: way.to.themain)

 

@alexjvan
This could be due to you making a new instance of your main class somewhere in your plugin, such as new Main() where instead you're supposed to pass it in a constructor.
Although this might be the issue, it would be helpful if you could post your code

 

@N00BHUN73R @timtower
Sorry about that, here is a link to the GITHUB code repository. https://github.com/alexjvan/GA-API

@Ben_Mattis
No, I checked and I couldn't find anything of the sorts in my code.

 

@alexjvan
Are you sure you don't have another plugin with the same package name? Are you sure you never initialized the main class twice? Are you sure there is only one copy of this plugin in you server/plugins folder?

For some reason, it is seeming two classes that both extend Java plugin and have the same path. What I would recommend is having a server with no other plugins on it, comment out all the lines in the onEnable, and un-comment them until you receive an error. Once you do, you know that something regarding that line is creating a new main class instance.

 

@Zombie_Striker I tried that and it loaded fine the first time, but at the first command I tried to add on; it gave me the error again.

@timtower How do you get the config file for separate classes then?

 

@alexjvan
Then that means the first command is trying to recreate a main class. Can you post that class?

[Edit] Just making sure, there is only one class in your entire plugin that extends JavaPlugin? This issue has happened before.

 

That class is suppose to implement CommandExecutor not extend JavaPlugin. Check other command classes too.

EDIT: I see you did it in other classes too.. From what I see quiet a few in https://github.com/alexjvan/GA-API/tree/master/src/com/gmail/alexjvan/ga/api/acessentials/commands

 

Either, Multiple classes are extending JavaPlugin, Or, You have 2 of the same plugins in your /Plugins directory. Like @ArsenArsen said, When using multiple classes with commands, implements CommandExecutor is always good.

 

@Mindlessmink if he had two of the same plugin bukkit would load the one it found first, and say ambiguous plugin names for file1 and file2

 

@timtower Ok, thank you. That seemed to work

 

Okay @alexjvan. Please mark the thread as solved
